CHARLES W. RENNER', OF ALTOQNA, PENNSYLVANIA.

VENTILATOR.

Specification of Letters Patent.

Patented Jan. 12, 1915.

Application filed August 8, 1913. Serial No. 783,797.

To all whom it may concern Be it known that I, CHARLES W. RENNER, a citizen of the United States, residing at 720 Howard avenue, Altoona, in the county of Blair and State of Pennsylvania, have invented new and useful Improvements in Ventilators, of which the following is a specification.

This invention relates to car ventilation against the ventilators will rebound and enter the ventilators free of cinders.

Further objects of the invention will appear as the following description is read in connection with the accompanying drawings, which form a part of this application, and in which Figure 1 is a side elevation of an ordinary passenger car showing the device applied thereto and with certain of the ventilators open. Fig. 2 is a detail top plan view with parts broken away. Fig. 3 is a vertical sectional view taken on the line 38 of Fig. 1, looking in the direction of the arrows showing the ventilator in open posi tion in full lines and in closed position in dotted lines. Fig. 4 is a similar section on the line 4-4 of Fig. 1. Fig. 5 is a horizontal section taken on the line 5-5 of Fig. l.

Extending throughout the major length of the car body and secured to the vertical wall 1 between the deck 2 and the crown of the car is what is termed a deck plate 4 having a plurality of openings 5 arranged there in, which openings are in register with similar openings 6 formed in the vertical wall 1. These openings are provided with frames 7 flanged at the top and sides, as shown at 8 and 9, and afford a protection for the ventilator to be hereinafter described.

The lower end of the deck plate has an obtusely extending flange 10, while the upper edge is provided with an acutely extending flange 11 whose outer portion is bent downwardly and inwardly, as indicated at 12. Mounted within each of the openings are ventilator casings which are preferably constructed of a single sheet of metal bent to form a substantially triangular casing 13 having a front plate 15, as shown in Fig. 5. The outer or upper edges of the side plates 15 are formed on the arc of a circle and the side plates are pivotally connected to the flanges 9 adjacent their lower edges by means of the bolts or rivets 16. The lower end of the front plate 14 is provided with an offset lip 17 adapted to abut the deck plate below the lower edge of the opening therein so as to close the opening against ingress of any cinders when the ventilator is in the position shown in dotted lines in Fig. 3, and the outer edges of the side plates 15 are flanges, as shown at 18, to limit the inward movement of the ventilator, as will be readily understood from an inspection of Fig. 5.

Extending between the side plates are a plurality of angular deflector plates 19 which support a screen fabric 20 attached at its marginal edges to the side plates 15, to the front plate 14 and to a supporting bar 21 extending across the casing between the side plates 15. The front end of the fabric is bent at direct right angles so as to be conveniently secured to the front plate, while the rear marginal edge of the fabric is extended at an obtuse angle thereto to the outer edge of the side plates so as to prevent cinders from lodging on the screen when the ventilator is in open position. The front plate is provided with a suitable finger or hook hold 22 by which the ventilator may be opened or closed.

Secured to the deck plate between each pair of ventilators, or in other words, so as to alternate with the ventilators, are-cinder deflectors which comprise the vertically ar ranged mounting plates 23 which lie against each other throughout the major portion of their width and diverge, as shown at 24, to be attached to the deck plate, thus forming braces. The outer edges of the plates 23 are separated so that the deflector plates 25 may be inserted between the same and bolted or otherwise secured thereto. These deflector plates are arranged in parallelism throughout the major portion of their length and then diverge and are formed to provide separate funnel shaped members 26 which flare from the bottom to the top and are open to receive the cinders adjacent the body of the plates. flectors not only deflect cinders, but also coact with the ventilators when the car is going in either direction to force air into These cinder dethe cars. As the cinder laden air strikes the deflectors the cinders are caused by their velocity and a certain amount of air to whirl around in the funnels and pass out at the top. At the same time a considerable quantity of the air which is then freed of the cinders rebounds toward'the ventilator in front of it and enters the ventilator casing and is deflected toward the crown or extra room by means of the deflector bars or plates 19;

What is claimed is 1. In combination, a cinder deflector comprising a member having one of its ends formed to provide a flanged base, and its opposite end being formed with oppositely arranged funnels and ventilators arranged upon opposite sides of and engaging the flanged base of said deflectors.

2. In a ventilator, an apertured mounting member, a flange casing arranged in the aperture, a ventilator casing having quadrant-shaped sides presenting arcuate upper ends pivoted to the opposed faces of certain of the flanges of the casing, an imperforate end connecting the sides at the rear edge thereof, flanges on the free extremities of the sides and adapted for engagement with the last named flanges for limiting the movement of the casing, angular deflector barsarranged between the sides of the'casing, a foramino-us fabric resting upon the horizontal portion of the bars and sunk below the edge of the sides and disposed across the top of said casing, means for manipulating the casing, the said arcuate upper ends of theventilator casing frictionally engaging with the other of said flanges of the flanged casing for sustaining the former in adjusted position.

In testimony whereof I aflixmy signature in presence of two witnesses.
